untitled opinion in love sucks

is it the way he looks at you, the way he smiles, the feeling of love is rare and the 3 words are overused, maybe its just a nice way to say i care about you. although maybe it is real, my question is, in this world in 2020 how do you know that those 3 words are honest i think maybe people just say i love you when they dont mean it because its one less word then saying i care about you, or maybe it just makes someone feel better but what if its fake and someone really ends up loving you when youve really just meant i care about you the whole time
